new and u for Operati of which tl In Letter 21, 1890, is ratus for 0 either one of the three positions in which it is represented in Figs. 1, 2, and 3.

In the drawings, A is the box which incloses the movement, with one of its sides removed to expose the parts within.

B is the longitudinally-sliding operatingand the li mbination, bar, which extends through hearings or guides with two or ovable piv-. in the ends of the box, in which it can slide oted arms which are lon gitu din. during its gages and ting the 01 other, and

i o the parts rated, of a bar, which rection enssion, quitngages the ted by the freely.

C and D are the pivoted arms, adapted to be connected to the parts to be successively operated. These arms are pivoted to the box, the one at 00 and the other at 1 intermediate of their ends. At their lower ends they are jointed, the one to a rod 3 and the other to a operatingin position rod 25, which rods pass out through the box whenever m is disenand are to be connected in any usual or suitgaged froi part to be able manner to the switch semaphoresignals first opera e succeedor the like, which they are to successively oping part b 11 part, exerate. At their upper ends the arms have cept the o chislocked formed in them slots 0 c (l (1, each the counimmovably se in which terpart of the other, consisting each of a comthe words or disparatively long portion 0 or d, which when engaged tion of said the operating-bar of the particular apparatus Letters P ed by the represented in the drawing is in its middle operatingin such reposition is horizontal, and a shorter portion 0' lation to e. 16TH; of the or d, which stands at an angle of forty-five operatingent of the degrees, or thereabo'ut, to the longer porarm, and t from the o ing-bar w a move the c My pres upon the t is designe attained b the use of are there best be ex ence to i which Figure ism, with t its movcm the same, dle of its tion of th tion. The particular angle at which the two portions of each slot stand to each otheris not,however, material. WVhat is desirable is an angle of such degree that the pin 1) on the operating-bar B, which engages the slot, will move in the angular portion of the slot with ease and will throw the arm without undue friction and exertion. While the slots are the same in each arm, they occupy reverse positions in the box, inasmuch as the arms are pivoted to opposite ends of the box, the arrangement being such that while the pin 1) is traversing the horizontal portion of one slot it will be traversing the angular portion of the other slot. It is only while the pin traverses the angular portion of the slot that motion is imparted to the arm. So long as it traverses the horizontal part of the slot the arm is held motionless. Consequently the arms disengaged the operatactuate or nprovement aratus, and sult as that us without cars which se. It can d by referawings,- in

he mechanextreme of .levation of at the midlilte elevating-bar at must move in either direction successively, and whenever and so long as one arm is in motion the other arm is at rest and is locked against movement.

The arms 0 D are placed one on each side of the operating-bar. The pin 1) in the operating-bar extends crosswise through it and enters the slots of the two arms. E is the operating-lever,which is pivoted to the bottom of the box A at 2, extends up through a slot in the operating-bar B, and projects from the top of the box through alongitudinal slot therein of such length as to allow the needed range of movement to the operating-lever. The engagement of the lever with the operating-bar is effected by the cross-pin b, which passes through a longitudinal slot e inthe lever. The operating-lever is provided 7 with the usual spring lock or latch, consisting of the downwardly spring-pressed detentf, the stem-of which slides in a guide g on the operating-lever and is jointed above this guide to connecting-rods h, which are at their upper ends jointed to the elbow of an angle-lever t', having its forked lower end pivoted to the operating-lever at to, with its upper end in proximity to the handle of the operating-lever, so that it, together with the handle, may be grasped by the operator. Pressure upon this portion of the angle-lever raises the detent f, so as to disengage it from any one of the three notches j in the segment-plate 7c, over which the detent moves when the operating-lever is actuated. Projecting upwardly from the detent-stem is a rod Z, the upper end of which plays through a guide m on the operating-lever. This rod is surrounded by a spiral spring .5, confined between the guide on above and a shoulder on the detent-stem below. This spring presses the detent downward. When the parts are in the position shown in Fig. 1, the arm D is thrown forward, with the pin b in the angular portion cl of its slot. In moving the operating-lever E from the position shown in Fig. 1 to the opposite extreme the arm D is first operated by the pin b moving in the angular portion cl of its slot, with the efieot of retracting the lower end of this arm, the arm 0 meanwhile remaining at rest and motionless by reason of the pin 17 passing through the horizontal portion 0 of its slot. This continues until the operating-lever has reached the middle of its movement, as seen in Fig. 2, at which time the pin b has just reached the horizontal portion at of the slot in arm D and is just about to quit the horizontal portion 0 of the slot in arm 0. Further movement of the operating-lever in the same direction to the extreme position shown in Fig. 3 will have the effect of throwing the arm 0 to the position indicated in that figure by reason of the pin 19 traversing the angular portion 0 of the slot of that arm, while the lever D is still held motionless in the position it occupies in Fig.2, because of the passage of pin 6 through the horizontal portion (1 of its slot. Thus each arm is operated successively and each is locked firmly against movement while the other is being operated. I

Having now described my invention and the best way now known to me for carrying the same into effect, what I claim herein as new and of my own invention is as follows:

In apparatus for operating railway signals, switches, and the like, the combination, with two independent vibrating pivoted levers to be connected to the parts which are to be successively operated, each lever being provided with a slot having a longitudinal and an angular or oblique portion, of a longitudinallymovable-operating-bar having a pin to engage each of said slots, the arrangement being such that whenever and so long as the pin is traversing the angular portion of the one slot it shall be in the longitudinal portion of the other slot, as and for the purposes hereinbefore set forth.

In testimony whereof I have hereunto set my hand this 26th day of May, A. D. 1890.
